摘要
本文研究了用Moran几何因子设计反褶积滤波器,提出了用该滤波器处理感应测井信号的相量反褶积方法.该方法利用测量信号中的实部分量和虚部分量,对围岩效应和趋肤效应同时进行校正,从而提高地层电导率的测量精度,为了验证其有效性,对俄克拉何马和北坡(North Slope)两种假想地层进行了计算机仿真.相量反褶积方法为现场快速地进行围。岩效应和趋肤效应校正提供了一种新的算法。
A phasor deconvolution method for the deconvolution filter based on Moran geometrical factor is analysed. The method is provided for processing the measured signal from induction log, and used to correct for both the shoulder effect and the skin effect by using the realcomponent and the imaginary component of the measured signal, thereby improving accura-cy of the formation conductivity measurement. Tn order to attest to applicability of the tech-nique, Oklahoma and North Slope simulative formations are modelled by computer. Thephasor deconvolution method provides a new algorithm for fast automatical correction forthe shoulder effect and the skin effect.
